小叶红叶藤的化学成分

Chemical Constituents from Rourea microphylla

目的:研究小叶红叶藤Rourea microphylla(Hook.&Arn.)Planch.的化学成分。方法:应用多种层析方法进行分离纯化,通过1HNMR、13CNMR等波谱技术确定化合物的结构。结果:分离并鉴定了9个化合物,分别为:23-羟基白桦酸(Ⅰ)、熊果酸(Ⅱ)、hederagenin(Ⅲ)、(E)-ferulic acid nonacosyl ester(Ⅳ)、瑞香素(Ⅴ)、山柰酚(Ⅵ)、芦丁(Ⅶ)、正三十一烷醇(Ⅷ)、1-hexacosanoyl glycerol(Ⅸ)。结论:所有化合物均为首次从该属植物中分离得到。

AIM： To investigate the chemical constituents fromRourea microphylla. METHODS：Column chromatographic techniques were used for the isolation and purification of chemical constituents of the plant and the structures were elucidated by spectroscopic analysis. RESULTS： 9 compounds were identified as 23-hydroxybetulinic acid （Ⅰ）, ursolic acid （Ⅱ）, hederagenin （Ⅲ）, （E）-ferulic acid nonacosyl ester （Ⅳ）, daphnetin （Ⅴ）, kaempferol （Ⅵ）, rutin （Ⅶ）, 1-hentriacontanol （Ⅷ）, 1-hexacosanoyl glycerol （Ⅸ）. CONCLUSION： All compounds were isolated from this genus for the first time.
